DENNIS HAYES, OF NEW YORK, N. Y.

PUMP.

Specification of Letters Patent'No. 31,804, dated March 26, 1861.

To all 'whom it may concern:

Be it known that I, DENNIS HAYES, of the city, county, and `State of New York, have invented a new 'and useful Improvement in Pumps; and I -do hereby declare that the following is a full, clear, and exact descrip tion' of the same, reference being had to the annexed drawings, making a part of this specication, in which- Figure l is a vertical central section of my invention; Fig. 2 a horizontal section of the same, taken in the line m, a3, Fig. l; Fig. 3 a detached view of one of the valves.

Similar letters of reference indicate cor responding parts in the several figures.

The object of this invention is to construct and arrange the valves of double acting pumps in such a way that they may be readily adjusted in proper position in the pump and readily detached or removed therefrom, and also fitted in the pump with but little labor and expense, the invention thereby admitting of the repairing of the valves when necessary with but little trouble and also admitting of the ready application of new ones when required, so that the pump may always be kept in proper working order at a mere nominal cost and without involving any material delay or loss of time.

To enable those skilled in the art to fully understand and construct my invention I p will proceed to describe it.

A. represents a pump cylinder which is provided with two vwater passages B. C. said passages being at opposite sides of the cylinder and communicating with it at its upper and lower ends as shown clearly in Fig. l.v The cylinder A. is provided with a piston D. which may be of the usual or any proper construction, the rod E. of the piston working through a stuiiing box F.

The water passages B. C. have holes or openings of taper form made through them transversely and directly opposite the induction and eduction passages I. J. These taper openings are reamed or made perfectly true which may be done with great facility as the necessary implements may be readily applied for the purpose. These taper openings receive taper or conical plugs G. H. each of which is formed of two heads b, b, of circular form and of such diameter as to close the orifices of the taper holes in which the plugs are fitted, the heads b, of course having their peripheries of a taper form corresponding to that of the orifices they fill. This will be fully understood by referring to Fig. 2.

The heads b, b, of each plug G. H. are connected by two parallel plates: a, a, and theplug Gr. has a puppet valve Knitted in it, said valve being a double one or formed of two heads d, ci, attached to a common stem, and fitting alternately over opening c, in the plates a., a, which are the valve seats, see more particularly Fig. 1. The plug H. is also provided with a puppet valve L. The latter however has only one head e, and it is placed on its stem between the plates a, a, of the plug H. so as to cover alternately the openings c, in. said plates. The heads (l, d, of the valve K. it will be seen are at the outer sides of the plates a, a. By referring to Fig. l, it will be seen that the plugs G. H. are fitted in their respective openings so that the spaces between their plates a., will coincide respectively with the induction and eduction passages I. J.

The operation is as follows: As the piston D. ascends, the water above it within the cylinder A. is forced down the passage C. and through the openings c, in the upper plate a, of plug H. the perforations in the lower plate of said plug being closed by the valve L. which yis forced down by the pressure of water in C. and the suction in the lower part of cylinder A. Vhile the piston D; moves upward and forces the water above it out from the cylinder through the passage C. and pipe J. the valve K. is also forced down so as to leave the openings c, in the lower plate a, of the plug G. open and the openings c, in the upper plate a, closed as shown in Fig. l. The water therefore as the piston ascends passes through the induction pipe I. down through the lower openings c, into passage B. and thence into cylinder A. iilling its lower part beneath the piston as the water in the part above is forced out from it. As the piston descends a reverse action of the water takes place as will be readily seen, the openings 0, in the lower plate a, of plug G. being closed while the openings c, in the upper plate a,

of said plug are open, the water passing from the induction pipe I up through B. and filling the upper part of the cylinder A. while the water in the lower part of the cylinder below the piston D. which water was drawn into the cylinder at the previous ascent of the piston, is forced up passage C. l tive of the construction and arrangement of 20 and through the openings o, in the lower plate a, of plug G.

Thus it will be seen that a very simple In case the valves require to be repaired,

the plugs G. II. may be removed with the greatest facility and readily inserted in theV passages B. C. while the plugs being of true taper form and the openings in the passages B. C. of corresponding form the plugs may always be tightly fitted in these openings. The valves also being of the puppet kind are more durable and not so liable to become deranged by use as the flap valve most generally used for such purposes.

I do not claim the arrangement of water passages B. C. with a cylinder A., irrespec- `the valves as herein shown and described,

for such device with a different arrangement of valves has been previously used.

What I claim therefore as new and desire to secure by Letters Patent is- 1. The placing of the valves K. L. in conical or taper plugs' G. I-I. which are fitted in the water passages B. C. substantially as and for the purpose set forth.

2. The combination of the double valve K. with the single valve L. and the conical plugs G. II. arranged for joint operation as and for the purpose set forth.

DENNIS HAYES.
